Re: Should I go back to my husband?
This.
Also, I think it’s not a good idea to do a trial getting back together because if it doesn’t work out, it will be messy for the kids again. And who will be blamed? Given that you already feel some (misplaced) guilt. It seems like everything is pretty stable right now and you’re doing fine. If he marries again (which is unlikely), I doubt he’ll stop being part of the kid’s lives.
